Abstract
A combination of a durable base and a disposable bowl for mixing of ingredients by a cosmetician. The base provides for the base and bowl to be free-standing so that the cosmetician can conveniently mix ingredients for hair coloring preparation, for example, and can also access the mixed hair coloring preparation using only one hand, and without having to hold the bowl or base in position on a countertop. An integrally molded, radially, outwardly extending planar lip around the periphery of the top of the disposable bowl provides rigidity to the bowl, while cooperating features such as a radially extending key and divot respectively defined by the base and bowl insure that the bowl is non-rotational relative to the base. The bowl may be a light push-fit or snap-fit into the base to further maintain the desired secure attachment of the bowl to the base during use. On the other hand, a notch or recess in the base provides for convenient removal of the bowl from the base for disposal.
Description
- 1. Field of the Invention
- This invention relates generally to facilities for mixing ingredients used by a cosmetician for coloring of a client's hair. More particularly, this invention relates to a durable base or holder for resting on a countertop and having an opening or recess for snugly receiving and holding a disposable bowl. The disposable bowl is non-rotationally retained by the base so that hair coloring ingredients may be conveniently mixed in and dispensed from the disposable bowl.
- 2. Description of Related Art
- Hair coloring procedures performed by a cosmetician often require ingredients to be mixed preparatory to the application of the hair coloring solution or preparation to the client's hair. Traditionally, cosmeticians mix hair coloring ingredients in a reusable mixing bowl with a reusable spatula or other implement. Reusable bowls, however, may harbor many disease producing microbes, which without proper precautions can transfer from one client to another. This is particularly the case with a plastic mixing bowl, the inner surface of which becomes scratched and scarred with continued use. The scratches and scars on the inner surface of the mixing bowl provide places in which microbes may be hidden to be passed to a successive client. In part for this reason, some of the companies which supply hair coloring preparations to cosmeticians also make appropriately sized plastic mixing bowls available to cosmeticians at low cost or for free. But, these mixing bowls are not supplied in sufficient quantity or at a sufficiently low cost that the bowls may be used only once and then discarded. Thus, the plastic mixing bowls in common use by cosmeticians receive many uses before they are discarded, and present the risk of microbes being passed from one client to successive clients.
- In order to reduce the risk of cross contamination by such microbes when a durable mixing bowl is reused, it is necessary to carefully clean the bowl by a complex and time-consuming procedure. That is, each bowl is washed in warm, soapy water, rinsed and dried. Then the bowl may be sprayed with a disinfectant and allowed to air dry for several minutes. When the reusable mixing bowl is to be used again, it should be rinsed again under running water to remove any residual disinfectant. As will be apparent, the requirements for personnel time makes this an inefficient and expensive process. Also, as was mentioned above, once the inner surface of a plastic mixing bowl becomes scratched or scarred, then effectively cleaning of this mixing bowl becomes essentially impossible.
- Another consideration is that the conventional plastic mixing bowls in use by cosmeticians are small, light, and have a relatively small base. This makes the conventional bowls likely to tip and spill the contents of the bowl, especially if the cosmetician attempts to either mix ingredients in the bowl without holding it in one hand while mixing with the other, or if the cosmetician attempts to dispense the mixed preparation from the bowl while the bowl rests on a countertop. Thus, the conventional plastic mixing bowls are inconvenient in that they often require both hands to be used, at a time when the cosmetician would like to have a hand free.
- U.S. Pat. No. 6,672,248 is believed to disclose a disposable bowl to be employed in the preparation of ready-to-eat pet food. However, this bowl appears to have no utility for mixing and dispensing hair coloring preparations.
- Similarly, U.S. Pat. No. 6,116,772 appears to disclose a disposable bowl and spatula for use in a dental office. This disposable bowl is free standing and would appear to require a user of the bowl to hold the bowl in one hand while the other hand is used with the spatula to mix ingredients in the bowl. A mixing bowl supported on a base allowing one hand to be used for mixing of ingredients in the bowl, and after mixing is complete, to allow one hand to be used for dispensing the preparation from the bowl, is desired.
- On the other hand, U.S. design Pat. DES 342,350 appears to be adapted to hold a pair of pet feeding bowls, but the bowls are not held non-rotationally in the holder, so this holder would not conveniently allow mixing of ingredients in the bowls. Also, this pet feeding bowl holder includes handle portions which would interfere with use of the holder with a bowl in which ingredients were to be mixed and dispensed after mixing.
- None of the prior art discloses or suggests a durable base receiving and non-rotationally holding a disposable bowl for the mixing of hair coloring preparations, and from which the mixed preparation is conveniently dispensed after mixing. There remains a need for a base with a disposable bowl adapted for mixing hair coloring preparations and for optimizing the mixing process, and from which the mixed preparation can be conveniently dispensed after mixing is complete.
- Therefore it is an object of this invention to provide a base having a recess or opening for snugly and non-rotationally receiving a disposable bowl for mixing a hair coloring preparation.
- An object of this invention is to configure the base and bowl for optimized mixing of ingredients in the bowl using one hand, and after mixing is complete to allow dispensing of the mixed preparation from the bowl also using only one hand.
- Another object of this invention is to provide such a disposable bowl for use in the combination described above, and which is of sufficiently low-cost and low in material-use, that it may economically be disposed of after a single use.
- Still another object of this invention is to provide a disposable bowl with sufficient rigidity to allow mixing of ingredients in the bowl while the bowl is supported in a durable base.
- Accordingly, an object of this invention is to provide a disposable mixing bowl for mixing of hair color preparations, that is disposable so that cleanup operations are eliminated.
- Finally, an object of this invention is to provide a disposable mixing bowl for mixing of hair color preparations, that is disposable so that the possibility of passing microbes from one client to successive clients is completely eliminated.
- In accordance with one aspect of this invention a base and disposable bowl for mixing hair coloring ingredients or preparations comprises in combination, a durable base and disposable bowl for allowing ingredients to be mixed in and dispensed from the bowl while the combination rests upon a support surface such as a countertop. This combination comprises: a durable base member including a body defining an opening for receiving and substantially non-rotationally holding a disposable bowl member, and the base member further including facility for frictionally engaging the body upon a support surface. A disposable bowl member of the combination is formed of fine-dimension plastic material, and including a basin portion for being received into the opening and for receiving ingredients to be mixed in the disposable bowl portion, the disposable bowl member further including a radially outwardly extending flange portion circumscribing the basin portion and for being disposed adjacent to the body portion about the opening when the basin portion of the bowl member is placed into the opening. And the body portion and the disposable bowl member define cooperating means for substantially non-rotationally retaining the bowl member removably within the opening of the base member.
- In accordance with another object of this invention a method of mixing ingredients or preparations for hair coloring includes steps of providing a durable base member including a body portion defining an opening for receiving and substantially non-rotationally holding a disposable bowl member. Provided on the base member is a facility for frictionally engaging the body upon a support surface. Also provided is a disposable bowl member configured to be received into the opening of the durable base member and including a basin portion for receipt into the opening of the durable base member and for receiving ingredients to be mixed in the disposable bowl portion. The body portion of the base and the disposable bowl member are configured to define cooperating features for substantially non-rotationally retaining the bowl member removably within the opening of the base member, while the base member is frictionally supported upon the support surface so that ingredients may be mixed in the basin portion by a user utilizing only one hand without the base portion moving about on the support surface and without the bowl portion rotating relative to or removing from the base portion.
- Additional objects and advantages of the present invention will appear from a reading of the following detailed description of a particularly preferred exemplary embodiment of the invention, taken in conjunction with the appended drawing Figures, in which like reference numerals refer to like parts, and in which:
-
FIG. 1 provides a perspective view of a base and disposable bowl embodying the present invention; -
FIG. 2 provides a perspective view of the base portion seen inFIG. 1 ; -
FIG. 3 is an end elevation view of the base and disposable bowl seen inFIGS. 1 and 2 ; -
FIG. 4 is an elevation view of a disposable bowl as seen inFIGS. 1-3 ; -
FIG. 5 is an underside or bottom plan view of a disposable bowl as seen inFIGS. 1-4 ; and -
FIG. 6 is an illustration of an alternative embodiment of the invention, shown in fragmentary cross sectional view at an enlarged size. - Considering
FIGS. 1-5 in conjunction with one another, and noting that like reference numerals indicate the same or analogous features throughout the various drawing Figures, it is seen considering firstFIG. 1 , that a base andbowl combination 10 includes abase 12, receiving and non-rotationally supporting abowl 14.Base 12 is generally of U-shape (albeit an inverted U-shape) and includes atop plate portion 16 defining a generally circular opening 18 (as is best seen inFIG. 2 ). Thetop plate portion 16 is integral with and is supported by a pair of flange-like dependingleg portions 20 and 22. Eachleg portion 20 and 22 terminates in an inwardly extendingfoot portion foot portions foot portions base 12 has a frictional engagement via thefriction pads 28 with the counter top that will allow ingredients to be dispensed into and mixed in thebowl portion 14 without the base and bowl moving about or slipping away from a user. - In order to facilitate the base 12 being sufficiently heavy that it will frictionally engage upon the surface of a counter top via the
friction pads 28, it is desirable that the base 12 be fabricated of a somewhat heavy and sturdy material. For this reason, as well as for aesthetic reasons, it is preferred that the base 12 be made of 14 or 16 gauge stainless steel, although the invention is not so limited. Alternatively, thebase 12 may be made of formed plastic sheet material, such as Lexan® or acrylic sheet material, or may be injection molded, if desired. Added weight may be added to or incorporated into the base 12 to assist it in being heavy enough to facilitate frictional engagement with a countertop. In each case, it is to be noted that thebase 12 has at top plate 16 a certain thickness or vertical extent, providing for thebowl 14 to engage within opening 18 with thebase 12. It is further to be noted that the preferred embodiment ofbase 12 defines a pair of exposed side surface (i.e., the sides of dependinglegs 20, 22) which may conveniently carry product advertisements. This is a particular feature of the present invention which may make it attractive for adoption by one or more of the companies making hair coloring products in order to advertise their products to consumers. Thus, thebase 12 and itsdisposable bowls 14 may be supplied to cosmeticians for free or at a very inexpensive price by one or more of these hair coloring companies, much like the deficient conventional plastic mixing bowls are presently so supplied. - Further considering
FIG. 2 , it is seen that theopening 18 is mostly (but not fully) circular. That is, theopening 18 is not fully circular because this preferred embodiment includes a circumferentially and radially inwardly extendingkey portion 30, which is integral with thetop plate portion 16 of thebase 12. Generally aligning with thekey portion 30, thetop plate portion 16 preferably defines a notch orrecess 32 extending radially toward theopening 18, and which if partially overlapped by a radially outwardly extendingflange portion 34 of thebowl 14. That is, thebowl 14 includes abasin portion 36 extending downwardly through theopening 18, and which may receive and hold contents for thebowl 14, and the radially outwardly extendingflange portion 34 which rests upon thetop plate portion 16. - Considering
FIGS. 3-5 especially and in conjunction with one another, it is seen that thedisposable bowl 14 is most preferably formed of thin or fine-dimension plastic sheet stock, which may be blow-molded or vacuum formed (for example) into the shape seen in these drawing Figures, although the invention is not so limited. Thedisposable bowl 14 includes abasin portion 36 terminating in a radially outwardly extendingflange portion 34, as was described immediately above. However, in order to insure that thebowl 14 is non-rotationally supported by thebase 12, thebowl 14 also includes a radially inwardly extending shallow recess ordivot 38, into which thekey portion 30 is received when thebowl 14 is received into opening 18 ofbase 12. Thebowl 14 may include additional or different features which assist in retaining thebowl 14 inopening 18, as will be further described below. That is, viewing particularlyFIG. 4 , theouter wall portion 40 of the basin part ofbowl 14 may include an essentially cylindrical portion or band (indicated onFIG. 4 by the arrowed numeral 42) which is disposed immediately below theflange portion 34. In order to assist in retainingbowl 14 inopening 18, theportion 42 may define an outer diameter which is just slightly larger than the inner diameter of opening 18 defined bytop plate 16 of thebase 14. In this way, a light push-fit of thebowl 14 intoopening 18 is established. That is, a user of thebase 12 andbowl 14 would, when placing a new disposable bowl into theopening 18 need to push thebowl 14 into theopening 18, seating theflange portion 34 on thetop plate 16, and seating theband 42 within theopening 18 oftop plate portion 16. This light push-fit of thebowl 14 intoopening 18 will assist in retaining thebowl 14 inopening 18, but will not prevent the used bowl from being removed from the base 12 by grasping and lifting the portion offlange 34 exposed atnotch 32. - On the other hand,
FIG. 6 illustrates an alternative construction for the disposable bowl. InFIG. 6 , features which are now familiar are illustrated using the same reference numeral used above, and having a prime (′) added. ViewingFIG. 6 , it is seen that an alternative construction may be effected for thewall portion 40′, such that a circumferential band of slightly reduced diameter is defined at 42′, and such that when a larger diameter lower portion of thebowl 14′ (i.e., immediately below theband 42′) when pressed through theopening 18, this action results in thebowl 14′ “snapping” into place into opening theopening 18. When thebowl 14′ is snapped into place in thebase 12, theflange 34′ is adjacent to thetop plate 16 of thebase 12. - With either a light push-fit or snap-fit of the bowl into the
opening 18, the bowl 14 (or 14′) will be securely retained within thetop plate 16 of thebase 12. Thus, it may be desired to make the opening 18 (and basin portion of bowl 14) purely circular in plan view, and dispense with the use ofkey 30 anddivot 38. But, regardless of whether a key and divot, a push-fit, or a snap-fit of thedisposable bowl 14 intobase 12 is utilized, thebowl 14 is secure in the base such that a cosmetician may mix ingredients in the bowl and dispense mixed ingredients from this bowl using only a single hand, if desired. Thus, the use of this inventive base and bowl combination affects a considerable improvement in convenience for the cosmetician. Further, the client enjoys an improved safety because thedisposable bowl 14 is used only once and then is discarded. Thus, disease causing microbes cannot be passed from one client to the next as with a conventional re-usable mixing bowl. - Further to the above, viewing
FIG. 5 particularly, it is seen that the bowl 14 (or 14′) defines a centrally located outer flat orfloor 44, such that the bowl 14 (or a stack of nested bowls) will set upright on a countertop. This allows the bowl to be set on a countertop even if not supported in thebase 12 without the bowl tipping over and spilling its contents. - In the use of the
base 12 andbowl 14, it is common for a cosmetician to desire to dispense hair coloring preparation into thebasin 36, and to there mix this preparation with a carrier liquid or solvent, such as water or other solvent. This mixing is conducted prior to the cosmetician dispensing the hair coloring preparation from thebasin 36 onto the client's hair, usually using a small brush. In both instances, the cosmetician desires to effect the mixing and dispensing with one hand, if possible, so that the other hand can be used in preparing the client's hair to receive the hair coloring. Thus, the stability of the present base and bowl combination is important to the successful use of the present invention. Further, because at least some of the hair coloring preparations are in a paste form before mixing, the somewhat sticky paste could cause thebowl 14 to stick to a mixing implement and lift out of thebase 14, or to turn with a mixing implement while remaining in thebase 14. Both of these undesirable possibilities are addressed by the present invention, which provides for the bowl to be sufficiently non-rotational relative to the base and to be retained by thebase 12. - While the present invention has been depicted and described by reference to a particularly preferred exemplary embodiment of the invention, such reference does not imply a limitation on the invention, and no such limitation is to be inferred. The invention is not limited to the particular preferred exemplary embodiment depicted and described, but is subject to modifications and alterations as will suggest themselves to those ordinarily skilled in the pertinent arts. The invention is intended to be limited by the spirit and scope of the appended claims, which provide a definition of the invention.
